Find contentThis game seriously have alot of potential, i remember playing it when it came out - i have around level 15 character. All the game really needs is stable updates.
They could also try contacting youtubers (mmos.com, mmobomb, etc) or even paying some youtuber with high subscriber count some $ to play the game, that will put alot of attention towards the game aswell, but do it after you have done few updates, so new player can accually see you guys put effort in to the game. Current website looks kinda sad as last update is from 2015, if i am not mistaken.
Much love!
